Chapter 12 Enhancing Decision Making  491


               survive, strong forces within organizations resist making decisions calling
               for major change. Decisions taken by a firm often represent a balancing of
               the firm’s  various interest groups rather than the best solution to the
                 problem.
                  Studies of business restructuring find that firms tend to ignore poor
                 performance until threatened by outside takeovers, and they systematically
               blame poor performance on external forces beyond their control such as
                 economic conditions (the economy), foreign competition, and rising prices,
               rather than blaming senior or middle management for poor business judgment.


               HIGH-VELOCITY AUTOMATED DECISION MAKING

               Today, many decisions made by organizations are not made by managers, or
               any humans. For instance, when you enter a query into Google’s search engine,
               Google has to decide which URLs to display in about half a second on average
               (500 milliseconds). Google indexes over 50 billion Web pages, although it does
               not search the entire index for every query it receives. The same is true of
               other search engines. The New York Stock Exchange spent over $450 million in
               2010–2011 to build a trading platform that executes incoming orders in less than
               50 milliseconds. High frequency traders at electronic stock exchanges execute
               their trades in under 30 milliseconds.
                  The class of decisions that are highly structured and automated is
                 growing rapidly. What makes this kind of automated high-speed decision
               making  possible are computer algorithms that precisely define the steps
               to be followed to produce a decision, very large databases, very high-speed
               processors, and software optimized to the task. In these situations, humans
               (including  managers) are eliminated from the decision chain because they
               are too slow.
                  This also means organizations in these areas are making decisions faster
               than what managers can monitor or control. Inability to control automated
               decisions was a major factor in the “Flash Crash” experienced by U.S. stock
                 markets on May 6, 2010, when the Dow Jones Industrial Average fell over
               600 points in a matter of minutes before rebounding later that day. The stock
                 market was  overwhelmed by a huge wave of sell orders triggered primarily
               by high-speed computerized trading programs within a few seconds, causing
               shares of some companies like Procter & Gamble to sell for pennies. The past
               few years have seen a series of similar breakdowns in computerized trading
               systems, including one on August 1, 2012 when a software error caused Knight
               Capital to enter millions of faulty trades in less than an hour. The trading glitch
               created wild surges and plunges in nearly 150 stocks and left Knight with $440
               million in losses.
                  How does the Simon framework of intelligence-design-choice-implementa-
               tion work in high-velocity decision environments? Essentially, the  intelligence,
               design, choice, and implementation parts of the decision-making process are
               captured by the software’s algorithms. The humans who wrote the software
               have already identified the problem, designed a method for finding a  solution,
               defined a range of acceptable solutions, and implemented the solution.
               Obviously, with humans out of the loop, great care needs to be taken to ensure
               the proper operation of these systems lest they do significant harm to organiza-
               tions and humans. And even then additional safeguards are wise to observe the
               behavior of these systems, regulate their performance, and if necessary, turn
               them off.
